Unable to download Ubuntu Updates

@kiekar did you try just with ipv4

I believe

apt-get -o Acquire::ForceIPv4=true update

Can you even ping that IPv6?

Still can't download

 Could not connect to ca.archive.ubuntu.com:80 (91.189.91.38), connection timed out Could not connect to ca.archive.ubuntu.com:80 (91.189.91.39), connection timed out

I am not able to ping IPv6. I don't use IPv6

Thanks

Well your linux box thinks it has Ipv6 or it wouldn't try to talk to it - which from your apt output it was trying to.

You, me, and every body else do not use IPv6.

But if this was taken from your (you ;) ) Ubuntu, then 'you' use IPv6 :

Reading package lists... Done

2001:67c:1562::18

is an Pv6 adres.
Ask the admin the Unbuntu system to disable IPv6 if needed.

So IPv4 is also blocked.

Let's start over.
pfSense, out of the box, does not block anything from it's LAN interface.
This means that any destination IPv4 'from 1.1.1.1' to '255.255.255.255' can be used by any LAN based device.
Check that this is the case.
We know it's the case, what counts that that you see for yourself this is true.

Now, change settings, install pfSense packages etc.

Check again.
Now, when you see issues like "Could not connect to ca.archive.ubuntu.com:80 (91.189.91.38)" you know where things went wrong.

I know, this seems a bit silly, but problem solving is based upon chopping everything in small steps, and analyse them one by one. You'll find the issue - and better : why it happens. The 'what to do' will even be easier.

@kiekar Since you are manually editing whitelists, you're going to want to use the "Force - Reload- All" option rather than "Force Update". Reason being is your whitelists are stored locally. Force Reload will load these local file edits to these whitelists to be able to load them. Force Update will "download" only the external files/lists/feeds that need updated from outside of your box, it will not reload the locally edited whitelist files you are altering. Without Force Re-loading after making manual whitelist edits will end up causing your "domain cache" to be offset line for line against the "IP cache" for however many whitelist lines are edited/added, and in the past on both of my boxes would then result in "google.com" for example pointed to a different websites IP address and loads the wrong data and webpage instead. Yes running a "Force Reload All" will take longer for it to run than "Update" but it is needed when manually editing local internal files/whitelists. Update is for externally downloaded feeds/blacklists

@smolka_J There may also be a chance these particular Ubuntu domains may not even be needed to be whitelisted once a Force Reload All is ran and completes. I am on Ubuntu Server 22.04 also, and have 11.4 million domains in my DNSBL blacklist along with 840,000 IPs blocked and whatever's leftover caught by 886 lines of REGEX blocking, and the ONLY Ubuntu domain I have in my DNSBL whitelist is "login.ubuntu.com" and updates work just fine. You may want to go to Services>DNS Resolver>Custom Options and add the following lines to Custom Options to not resolve IPv6 back to clients and then reboot your pfSense box for Unbound to load them -

server:
do-ip4: yes
prefer-ip4: yes
do-ip6: no
prefer-ip6: no

Thank you all for your input and pushing me to find a solution.

The issue resided at the GeoIP Top Spammers rule. I changed the Action from Deny Both to Deny Inbound which resolved my issue

Inbound : traffic coming IN = traffic that comes in your WAN.

By default : the WAN firewall rule list is empty, so : by default nothing comes in anyway.

The perfect solution would be : why do you even bother using the GEO IP list ?
Drop it, make things easier, and you'll be safe, fine, and less issue can arrive.

I changed the Action from Deny Both

Because you were afraid that you could actually send mail ( ? ) or interact with these IP's ?
What you've found out : Unbuntu package servers are listed on the GEO IP you use.
Strange, as these servers never send or push any traffic to you or anybody else. They work 'on request, initiated on your side'.
Conclusion : never fully trust list you obtained from 'somewhere'. Check them. And if checking is to hard, don't use them.

Because I have open ports to the public for my mail server and web server.

Thanks,

@kiekar

Right, that is a reason to use some (GEO) IP blocking for incoming connection on WAN.
